I would call Al at Hot Rod Scooters and just put the cylinder in a box and mail it to him along with the cylinder head. If you know of a piston to get then tell him about it.. and he'd get the piston and then bore the cylinder and do your ring gap for you so you can just bolt it on and go. You may have to follow up with the cylinder head later since he would need to know how high in the cylinder bore the piston goes before milling the head out.

He's a two stroke guy that's been doing it for years.. he knows about small displacement 2 stroke machine work.. local machine shops may not know how to deal with the tollerances of the smaller pistons and thin rings.

Oh.. and make sure to CALL Al and talk to him.. he's no good with the email. He will talk your ear off and make your head spin about stuff. Plus he'd be stoked to talk to a chick that knows what she is talking about with motor junk.

The next thing to figure out is if the Cento 3rd gear is roughly the same size as the Starstream 4th gear, because if so, it's probably not worth it to muck around with changing the gears.

If not, I gotta figure out if switching to Starstream gears is as simple as buying the 4th gear, tree (or whatever gears attach to on Centos, haven't dug that far into the engine yet), and 4-speed gear selector and slapping it all together.

If you get the piston free, you might be able to just rebore the existing cylinder to the next oversize......costs about $50 via Scooters O.........buy the next matching oversize piston and you're done.

Whole new stock cylinder is $100. After shipping the old one and buying a new piston.... have I saved any money? We'll see once I get the thing out/unstuck, until then, still looking for input/ideas/experiences with the available kits and what carbs/pipes/flywheels/etc must/should go with...
